METHOD, DEVICE AND SYSTEM FOR GENERATING A VIDEO SIGNAL Russian patent published in 2020 - IPC H04N5/262 G06T3/40 

FIELD: video processing.

SUBSTANCE: disclosed is a method of generating an output video signal (S_o) from a plurality of input video signals (S_i1,… S_im), containing corresponding sequences of input frames (S_i1[n]…S_im[n]) with the number of pixels for each input frame associated with the input resolution (R_i1…R_im), containing 3D spatial space virtual space associated with each pixel; setting, in 3D virtual space, a visualization point (X₀, Y₀, Z₀) and a rendering window; calculating corresponding pixel threshold density for pixels in a rendering window; determining combinations of input frames whose projections are partially overlapped in the rendering window; and selection from each frame combination of such a frame, which in the projection on the rendering window has a pixel density in the entire overlapping part greater than or equal to the pixel threshold density, or, in the absence of such a frame, selecting a frame which, when projected onto the rendering window, has the highest pixel density, in order to form an overlapping portion of the output frame.

EFFECT: generation of video signals from a plurality of input video signals in real time and possibility of using input signals with high resolution without concomitant accumulation of delays or without using considerable computational power.
